Gravitee is a self-hosted, open-source API management platform that governs REST, event-stream, and AI-agent traffic through one policy layer and developer portal. It suits platform teams that must secure gateways, Kafka streams, and LLM traffic under common governance instead of running a separate tool for each.[1][2]
Quick verdict
Gravitee earns a conditional recommendation for platform teams that need REST, Kafka, and third-party gateway traffic under one policy layer: official docs support the breadth, G2 reviewers rate it 4.7 with an easy portal, but Enterprise pricing is quote-only and the platform expects real operations know-how.[1][2][3]
Key features
Unified gateway for REST and event streams One gateway proxies REST APIs and exposes Kafka event streams as secured, governed APIs, so request and streaming traffic share the same management plane.[1][2]
Reusable policy studio The management console designs, applies, and monitors reusable policies for authentication, authorization, traffic control, and threat protection across every managed API.[1]
Federated governance without migration Federated management extends Gravitee governance to third-party gateways from AWS, Apigee, MuleSoft, IBM, and Confluent, so existing gateways stay in place while policies centralize.[1]
Developer portal with plans and quotas The publisher and developer portals let teams publish APIs, offer self-serve subscription plans, and enforce quotas on consumption.[1]
AI-agent traffic controls Agent management features proxy and govern LLM and MCP-server traffic, extending the same policy layer to AI agent calls.[1]
Enterprise identity and audit options Enterprise Edition adds SSO, MFA, role-based access with custom roles, audit trails, and multi-factor protection for the management plane.[1]
Observability and alerting Logging, metrics, tracing, dashboards, and the Alert Engine notify teams through Slack, PagerDuty, email, or webhooks when governed traffic misbehaves.[1]
Docker and Kubernetes deployment The platform runs locally with Docker Compose for evaluation and on Kubernetes via Helm for production, in self-hosted, hybrid, or fully managed modes.[1]
Who will love it
Platform teams unifying API governance Teams that run REST, Kafka, and third-party gateways side by side get one policy layer and portal instead of three separate governance setups.[1][2]
Enterprises needing audit and SSO Organizations that require SSO, MFA, custom roles, and audit trails for compliance will value the Enterprise management plane.[1]
Builders exposing events as products Teams that want Kafka streams consumable like REST APIs, with plans and quotas, will use the event gateway and developer portal pairing.[1]
Who should avoid it
Teams wanting a tiny single-binary gateway Gravitee is a multi-component platform with a gateway, management API, console, and datastores, so teams that want one lightweight binary should look elsewhere.[1][2]
Buyers wanting public per-seat pricing Enterprise pricing is quoted rather than listed, so budget holders who need an instant monthly figure cannot self-serve a number.[1]
Non-technical site builders Policy design, federation, and event gateways assume API and infrastructure fluency; it is not a no-code website or app builder.[1]

Questions worth asking
What is the best Gravitee alternative for non-technical users?
Can I use Gravitee without writing code?
No. Gravitee is an API governance platform for engineering and platform teams; the developer portal serves API consumers, but designing policies, federations, and event gateways needs API and infrastructure knowledge.[1]
How much does Gravitee cost per month?
Gravitee does not publish flat monthly prices on its site; Enterprise Edition is quoted per arrangement and described as flat pricing with unlimited calls. The open-source core is free under Apache 2.0, so self-hosted teams can start at no license cost.[1]
